Make the front and back panels identically. Chain 8. Row 1: sc across. [7]. Rows 2 to 4: sc across. [7]. These rows form the lower body of the coffin. At the end of row 4, chain 2 at each end to widen the shoulders: on row 5, sc across 7, sc into the 2 chains at the end. Turn and add 2 chains at the other end too. Work row 6 across all 11 stitches. [11].
The shoulder is now the widest point. Rows 7 to 9: sc across. [11]. This is the upper body section. Row 10: decrease once at each end. [9]. Row 11: decrease once at each end. [7]. Row 12: decrease once at each end, sc across. [5]. The top of the coffin now tapers. Fasten off.
Make two identical panels. Hold them wrong sides together and sc through both layers around the entire perimeter, working 2 sc into each corner point. Slip stitch to join at the starting point and fasten off.
Embroider a small cross on the front panel with white or silver yarn, centring it in the upper body section.
Thread ribbon through the top corner stitch to create a hanging loop and knot it securely.
